But it would be such fun to reprise our success at getting the world not 
to use NAT, and at the same time make it impossible to get work done.

> A simple service that gives me the addresses of the people who should be in the alias, ready for copy/paste into a MUA, would do.  This still does not solve the problem of one chair sending a note to some document authors and the other chair wide-replying to that to offer some additional information, but it would be a start.

I think we can do better than that.  For one thing, many of the DMARC 
failures seem to be due to bad DKIM signatures which means something is 
changing the message bodies.  That seems like a bug we can fix.

Beyond that, we already have the revsrsible address rewriting hack I 
invented for the mailing lists which turns steve@aol.com into 
steve=40aol.com@dmarc.ietf.org.  It's ugly but it works and it is simple 
enough that you can undo it in procmail as you deliver your own mail.
